A high-performance liquid chromatographic method was developed and validated to determine liquiritin, hesperidin, and glycyrrhizin levels in a traditional Korean medicine, Pyungwi-san (PWS). Reverse-phase chromatography using a C18 column operating at 40oC, and photodiode array detection at 254 nm and 280 nm, were used for quantification of the three marker(More)
Asthma is characterized by difficulty in breathing because of the constriction of the smooth muscles of the bronchi, as a result of inflammation. In the present study, we focus on the protective effects of allantoin against ovalbumin (OVA)-induced lung inflammation in a murine allergic model, and assess cytokine release, eosinophilia, and mucus(More)
A high-performance liquid chromatographic (HPLC) method was developed for quantitative analysis of seven components, 5-hydroxymethyl-2-furaldehyde (1), albiflorin (2), paeoniflorin (3), liquiritin (4), ferulic acid (5), nodakenin (6), and glycyrrhizin (7) of Palmul-tang (PMT), a traditional Korean medicine. HPLC analysis was performed using a Gemini C18(More)
The effects of acupuncture on healing of deep second degree burns were compared to the conventional hydrocolloid dressing, Duoderm in mice. The expression level of inflammatory protein-1α (MIP-1α) was significantly reduced in the injured skin and the number of eosinophils in blood decreased significantly following the acupuncture treatment compared to the(More)
Increasing evidence that decreased bone density and increased rates of bone fracture are associated with abnormal metabolic states such as hyperglycemia and insulin resistance indicates that diabetes is a risk factor for osteoporosis. In this study, we observed that TallyHo/JngJ (TH) mice, a polygenic model of type II diabetes, spontaneously developed bone(More)
The aim of this study was to improve the anti-inflammatory activities of apigenin through co-treatment with resveratrol as a bioenhancer of apigenin. RAW 264.7 cells pretreated with hepatic metabolites formed by the co-metabolism of apigenin and resveratrol (ARMs) in HepG2 cells were stimulated with lipopolysaccharide (LPS). ARMs prominently inhibited (p <(More)
We have previously shown that benzo(a)pyrene inhibits the growth and functional differentiation of mouse bone marrow (BM)-derived dendritic cells (DCs) [Hwang, J.A., Lee, J.A., Cheong, S.W., Youn, H.J., Park, J.H., 2007. Benzo(a)pyrene inhibits growth and functional differentiation of mouse bone marrow-derived dendritic cells. Downregulation of RelB and(More)
OBJECTIVE To evaluate whether human papillomavirus (HPV) genotype is associated with poor prognosis of uterine cervical cancer treated primarily with radiotherapy. METHODS HPV genotyping was performed in 181 radiotherapy patients using SPF10 polymerase chain reaction and HPV reverse hybridization line probe assay. Univariate and multivariate Cox(More)
Mentha haplocalyx Briq., a commonly used herb in traditional Oriental medicine, has a variety of known pharmacological properties. However, neither the protective effects of Mentha haplocalyx ethanol extract (MH) against inflammation of the airway in an asthmatic model nor the mechanisms involved, have previously been reported. In the present study, an(More)
Asthma comprises a triad of reversible airway obstruction, bronchial smooth muscle cell hyperreactivity to bronchoconstrictors, and chronic bronchial inflammation. Clinical and experimental findings have established eosinophilia as a sign of allergic disorders. In the present investigation, we evaluated the anti-asthmatic effects of schizandrin and its(More)
